The invention discloses a tool for live change of a 220KV narrow base tower strain insulator string. The tool is formed by detachably connecting a triangular yoke plate clamp for connecting a triangular yoke plate, an insulating pull rod, a hydraulic lead screw, and a right-angle yoke plate clamp for connecting a right-angle yoke plate, wherein the triangular yoke plate clamp is used for connecting one end of the triangular yoke plate and the right-angle yoke plate clamp is used for connecting one end of the right-angle yoke plate to form a dual-clamping plate structure; the triangular yoke plate can be clamped and fixed between the two clamping plates of the triangular yoke plate clamp, and the right-angle yoke plate can be clamped and fixed between the two clamping plates of the right-angle yoke plate clamp. The tool disclosed by the invention is simple in structure, and easy to mount and operate; the live working method can reduce maintenance difficulty and improve efficiency, and is firmer to connect, hig
